Description of Kinesis Maxim Split Adjustable Keyboard:

The award winning Kinesis Maxim adjustable ergonomic computer keyboard is the only ergonomic keyboard licensed to use the Microsoft "combo" USB/PS2 technology. All Maxim keyboards are shipped as native USB, but include a PS/2 adapter for those systems that only have a PS/2 port. One keyboard now connects to any PC OS as well as legacy PS/2 systems.

Much narrower and more versatile than "natural-style" keyboards. The Maxim accommodates a wide range of user preferences.

Kinesis KB210USB Maxim Features:

Variable Split: Much more flexible than "natural-style" keyboards; no adaptation required. Select any opening between 0 and 30 degrees, a wider range than "natural-style" keyboards. By "splaying" the keyboard modules it positions your wrist and hand in a neutral posture greatly reducing ulnar deviation.

Narrow Footprint: Your mouse is right where you want it - not at arms length! Even fully separated, the Maxim is narrower than the new "narrow" Microsoft Natural Elite. In a typical split configuration, the Maxim keeps your mouse significantly closer than with any "natural-style" keyboard, reducing over-reach issues.

Removable palm supports. Comfortably padded to take the weight off your shoulders without hurting your hands and eliminating wrist extension.
